Description

Two-way switch door device and refrigerator having the same

Technical field

The present invention relates to the field of refrigerator manufacturing technology, and in particular to a bidirectional switch door device and a refrigerator having the same.

Background technique

The refrigerator is a refrigeration device that maintains a constant low temperature, and mainly includes a casing, a storage compartment disposed in the casing and used for storing food, and a door body for closing the storage compartment, the door body being hingedly mounted by a hinge The casing is configured to open or close the storage compartment.

Currently, refrigerators circulating in the market are usually made to open or close the door only in a predetermined direction, for example, in a manner to open or close to the right, to open or close to the left. Here, the term "the way to open or close to the right" means that the hinge is connected to the right end of the door body such that the door body pivots about its right end, and the term "opening or closing to the left" means that the hinge is connected to the left end of the door body. The door body is pivoted about its left end. When the refrigerator is placed in a certain place, the door body can only be opened or closed in a predetermined direction. If there is an obstacle (for example, a wall, a household appliance, etc.) in the direction in which the door body is opened or closed, the user will be affected. usage of. In order to facilitate opening or closing the door of the refrigerator, the user usually needs to move the household appliance or move the refrigerator, often causing unnecessary trouble to the user. In addition, a one-way open or closed refrigerator cannot satisfy both the right-handed person and the left-handed person.

In order to solve the above problems, the refrigerator manufacturer has developed a refrigerator that can open the door in two directions, and the refrigerator is realized by separately installing hinges on both sides of the cabinet. When the user needs to change the door opening mode, the door body is detached from one side of the box body and then installed to the other side of the box body. However, such an operation process can be completed by a general user and requires a special maintenance worker to complete. Therefore, the user still feels inconvenience in the process of using.

In view of the above problems, it is necessary to provide a new two-way switch refrigerator to solve the above problems.
